OT-8651, 12 bit; 4xAO, 0-10 V, ±10 V, 0(4)-20 mA

AO 4x AO
Picture Variant Variant description
OT-8651 - expansion module contains 4 analog outputs AO0 to AO3. The outputs have separate terminals and are output as voltage with a range of 0 ÷ 10 V, as well as current with a range of 0 ÷ 20 mA. However, the output cannot be connected as both voltage and current at the same time. Loads of both types are connected against the ground. The resolution is 12 bits, the output value can be set in percent of the maximum value, in engineering units or fullscale (0-30000). The current outputs have an indication of the disconnection of the current loop (open circuit) on the front panel. Current loop disconnection detection is only functional when the output current is set to at least 100 µA.
The analog outputs are galvanically isolated from the internal circuits and from each other. The module is equipped with a removable screwless connector with 17 terminals and with locking after insertion into the module.

The product must not be exposed to direct weather conditions during transport and storage. Malting of the product is only allowed in clean rooms without conductive dust, aggressive gases and vapors. The most suitable storage temperature is 20 ° C
Assembly description The installation of the TC800 system module is carried out by sliding it perpendicularly onto the DIN rail ČSN EN 50022 with busbar and locking latch in the lower part of the module. A more detailed description and mechanical drawings with dimensions are given in the documentation TXV 004 72.
Warning All external circuits connected to the module must meet the conditions for SELV circuits!

Module installation tools (-) 2 mm, flat screwdriver
Connection description An example of module connection is shown in the following figure.
Module operation
Module configuration The module is operated, set up and diagnosed from the Mosaic development environment.
Commissioning On the module, the DIP switch in the left part of the case sets a unique address within one frame. The module is fully ready for operation after inserting it into the frame and turning on the power supply.
Module diagnostics The basic diagnostic system of the module is part of its standard software. It has been in operation since the module power was turned on and works independently of the user. Diagnosed error states of the module and connected peripheral modules of the assembly are signaled in the status word of the module and on the module panel
Description The module does not require any maintenance under general installation conditions.
Notice Because the module contains semiconductor components, it is necessary to follow the principles for working with electrostatic sensitive components when handling the removed cover. It is not allowed to directly touch the printed circuit boards without protective measures !!!
Generally Warranty and complaint conditions are governed by the Terms and Conditions of Teco a.s.
Notice You must meet all the conditions of this documentation before turning on the system. The system must not be put into service unless it has been verified and confirmed that the machinery meets the requirements of Directive 2006/42 / EC for machinery, in so far as it applies to them.
